Fourteen years ago Grinker, Sr., Grinker, Jr., and Timberlake published a detailed study of mentally healthy young men, whom they called "homoclites." The data were obtained by means of interviews, questionnaires, and college reports. In an attempt to obtain large enough samples of normal controls for use in a program of research on schizophrenia, these subjects were sent questionnaires identical to those used on the schizophrenic follow-up studies.
Analysis of the results indicated that aside from a few cases of mental illness the homoclites, as a group, maintained their good health into the third decade of life. We therefore have a normal control group of 134 men available for use by other investigators in their research programs.
